Real Customer Reviews

Perfect for marathon training

This pack is working great. I am using it for marathon training. Slim and it doesn’t bounce hardly at all. Also love the neoprene material. I have not had any chafing. I do put bodily glide where the pack potentially may rub. I have worn this on a 17 mile run

Great Product

Great water pack for an active lifestyle.
I have been using it for trail running and have not had any problems with it rubbing or bouncing.
The only thing I can see it needing is a pouch to place energy chews.

Customer service is PHENOMENAL!

I purchased my DolfinPack mainly for Spartan OCRs and for my long runs. I researched several different brands and found this one to be a great fit for my needs. I have had it for about 7 months and I absolutely love how lightweight this product is, the material is breathable (need that in a Florida!) and it does the job. I did have to request a replacement after 6 months when I noticed that the seams started coming apart on one side and the strap began ripping. However, I still give this product 5 stars because the customer service is PHENOMENAL because within 24 hours of putting in my initial request (on a Sunday, no less) my replacement was already on its way to me. One thing I do wish it did have was an exterior pocket for fuel and/or keys so I don't have to put in the main pocket with my hydration pack.

This hydration pack is light and comfortable. I used it for an 8 mile Spartan

This hydration pack is light and comfortable. I used it for an 8 mile Spartan run and it did a fine job. Lately, I have taken out the reservoir and relied on the water at the water stations. Instead I have used it to carry gels and goos as well as any items (layers) I remove while running. Comfortable and versatile.

Lightweight, small, and easy to run with!

So I have only used this once, but I really loved my first experience with it! I have had others in the past and like so many elements of this one way better. I use this for longer distance runs or will use in the summer when its too hot to run without water.

I like the material, it feels very water friendly for all the sweat that I get on it ;) It was very lightweight and didn't jiggle around at all! Even the water in the bladder didn't bother me, I couldn't hear it over my tunes playing. I am slightly worried that the velcro will wear out, but I'll cross that bridge if it happens then!

The mouthpiece is very easy to bit down on and there is a on/off switch which is a really nice feature.

The position on the chest may be a little funky for women with larger breasts. While my chest is rather small, I did not have this issue, but due to the placement of the straps, I'm not sure if they would fit well under larger ones or make them uncomfortable?

But overall I like how small and lightweight this is! Perfect for just the right amount of water needed for a 2-3 hour run :)

Wore this for my first spartan beast and it was so light I sometimes thought I had low water. Filled it once on the 14 mile course and could even fit my Gu packs and nuun tablets inside the pouch!

Light weight

I bought this for my grandson for his birthday. He and his dad go on long hikes so this make things so much easier now that he doesn't have to carry his water bottle! It is very light weight.

These guys are great. Great product would highly recommend

These guys are great. Great product would highly recommend. I've run 2 Spartan races (Super and Beast) with this pack. With it being made from the lightweight material hardly knew it was on. Also was able to get some energy packs stuffed in with no problem.

The DolfinPack Lightweight does as it was advertised. Light and compact, I can see myself running with it on my back. Don't buy this product if you expect to carry big items in the pack with the water bladder filled. I fit a wallet, keys, and squeezed a 100 page 8"x 11" magazine in the pack with a little struggle. All in all, I can see myself using this item for many outdoor adventures with and without a shirt.

lightweight, secure, quality

My son gets so hot and dehydrated running. He asked me to find something that wouldn't bounce around. This has great padded straps and a cross strap to make sure it doesn't slosh around. He does need to make sure he gets ALL the air out before starting to run. He calls it burping the dolphin. Nice wide opening to clean it out. I put paper towels inside to let it air dry

In Lake Tahoe 10/1/16 in this and was extremely satisfied, light weight

Ran the Spartan Beast in Lake Tahoe 10/1/16 in this and was extremely satisfied, light weight, low profile and durable. The Velcro worked well and never came loose, only knock is if you use the dust cap the holder doesn't work, I brought my own Velcro strip to hold it in place while I ran. Overall great buy and will use it in all of the longer Spartan runs and in training. Also since there are no pockets I filled 3/4 full and there was plenty of room to put a Ziploc bag with my energy beans, salt tabs and beef jerky.

I absolutely love my DolfinPack

I absolutely love my DolfinPack! It's comfortable to wear and does the job I need. I mostly use it for Spartan Races, but have taken it on canoe and kayak outings, as well as runs around the neighborhood or on trails. The water bladder holds enough to get me through all my evens. It is easy to clean and doesn't hold smells (like from preworkout or BCAA powder). The neoprene pack washes clean after each race! I can throw my keys, snacks, or anything inside and am not concerned about losing them! I highly recommend this pack!

Done well so far in OCR

Needed a affordable but reliable pack for OCR racing, and so far this has done well. Took it through a 14 mile Spartan Beast and for a few laps (15 out of 25 miles) during a Battlefrog Xtreme. Fits tight, no extra bounces, and so far hasn't fallen apart anywhere even if wet and caked with mud. Only downside is lack of places to store nutrients if needed, but its sole purpose is hydration and it does that well!

Five Stars

Cute pack. Small just what I wanted

Awesome!

On the suggestion of a friend, I ordered this for the Spartan Super. I am small (5'3", 118 lbs.) and many other hydration packs are too bulky, take on too much water (during obstacles), or chafe. This pack is awesome! Extremely low profile with soft straps. It velcros across the front just under the breasts.

Note that there is no zipper pocket for fuel, but in the large pouch which contains the bladder, I put chews, gel, and a protein bar no problem. My Spartan teammate had that in hers plus compression sleeves and gloves.

Highly recommend!
